Treasury bond price gains are accelerating late Thursday morning after multiplereports that a Malaysian passenger airplane (no, not that one) has crashed near the Ukrainian border, with some reports saying it was shot down. The 10-year Treasury note is now up 15/32 in price, cutting its yield below the 2.5% level for the first time since early June to 2.482%, per Tradeweb data. That yield reached a 2014 low of 2.434% on May 28. The 30-year bond is up 1 1/32 to yield 3.293%, approaching its 3.286% 2014 low, also set on May 28.
